DBS50 Core INCREMENTAL ENCODERS
Product description
The DBS50 Core incremental encoder
features impressively high mechanical
exibility, excellent technical properties, and a number of variations. The
DBS50E has a face mount ange with
50 mm diameter and a solid shaft with
8 mm diameter. The housing diameter is
extremely compact at 37 mm and thus
saves valuable space. The face mount
ange offers 2 different mounting hole
At a glance
• Connection with universal cable outlet
• Face mount ange with 8 mm solid
shaft
• Face mount ange with 2 mounting
hole patterns and servo groove
• Compact housing diameter of 37 mm
with compact construction depth,
ange diameter 50 mm
patterns and a servo groove for mounting with servo clamps. The encoder has
compact dimensions and a universal
cable outlet that allows for cables to
run in an axial or radial direction. The
DBS50 Core incremental encoder is fully
compatible with the DDS50E incremental encoder.
• Various electrical interfaces: TTL/
RS-422, HTL/Push Pull and Open
Collector NPN
• Number of lines from 10 to 2,500
possible
• Temperature range: –20 °C... +85 °C
• Enclosure rating: IP 65
